OPERATING DEVICE FOR ELEVATORCARS.

SPECIFCATION forming part of Letters Patent No. 742,628, dated October 27, 1903. pplication filed June 23, 1903i Serial No. 162,745. (No model.)

To all whom t may concern:

Be it known that I, PATRICK F. FOLEY, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Operating Device for Elevator-Cars, of which the following is a full, clear, and exact description.

This invention relates to elevators; and it consists substantially in the construction, organization, and combinations of parts hereinafter particularly described and claimed.

The invention has reference more especially to devices for raising and lowering the cars of elevators; and one of the principal objects of my invention is to provide means for overcoming numerous disadvantages and objections found to exist with many other devices hitherto devised for similar purposes and also to provide devices of this kind which are exceedingly simple as well as comparatively inexpensive to manufacture and comprising few elements or parts, which are not easily broken o'r'dislocated nor liable to get out of order. v

A further object of my invention is to provide devices of the character referred to which are effective and reliable in use or operation, as well as easily controlled and regulated, and which also possess the capacity for long and repeated service.

The above and additional objects are attained by means substantially such as are illustrated in the accompanying drawings, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 represents-an embodiment of my improvements in vertical side elevation; and Fig. 2 is a perspective view representingmore clearly the embodiment of the plural operatin g-cables employed and the disposition of the different double guides or sheaves therefor.

BeforeA proceeding with a more detailed description it may be stated that vin the form of my improvements herein shown I employ suitable guides for preferably two verticallymovable frames which are caused to simultaneously rise and-fall for the purpose of effecting the lowering and raising of the car or cage of the elevator, said frames supporting thereon suitable guides or sheaves for one or more endless cables through the medium of which the frames are operated directly from a suitable motor. The car or cage of the elevator is connected with one of the movable frames by means of an independent cable, this latter, as well as the endless operating cable or cables referred to, working over suitv able stationary guides or sheaves therefor, as will presently appear, and while I have herein represented my improvements in a certainpreferred form itis apparent, of course, that I am not limited to the precise details thereof in practice, since immaterial changes may be made therein coming within the scope of my invention. The said rising and falling frames may `each be counterweighed relatively to the other, as well as to the cage or car, and in the use of Inore than a single end-V less operating-cable for said frames and car I preferably employ for each additional cable an independent adjusting device for takin gup slack produced therein from any cause, the first cable being kept taut by the weight of one of the frames, but which cannot be readily effected for a plurality of cables on account of unequal stretching thereof, all as will be apparent.

Specific reference being had to the accompanyin g drawings by the designating characters marked thereon, 1 1 and 2 2 represent duplicate sets of vertical guides or rails which are suitably supported in position with those of each set properly spaced apart, and located at the upper ends lof'said guides or rails, preferably one above the other, are the horizontal beams or timbers 3 and 4, which may be supported in any suitable manner. Working vertically between the guides or rails 1 1 is a slidable frame 5, constructed, preferably, of upper and lower horizontal members 6 and 7, (each preferably in duplicate, though but one of each is shown,) which are connected vertically by rods 8, upon whichmay be placed any desired number of counterweights 9`for the elevator car or cage 10, to be presently again referred to, it being noted that the sides of said frame at 11 are adapted to iit the said guides or rails 1 1. Similarly working' between the guides or rails 2 2 is another vertically-slidable frame 12, likewise preferably constructed of upper and lower horizontal members 13 and 14:, (each also being preferably in duplicate, though but one of each is shown,) which are connected vertically by rods 15, upon which may also be placed any desired number of counter-weights 16 for establishing proper balance of this frame with the frame first named, as well as with the said car or cage 10.

Preferably located between the guides or rails 1 1, at the base thereof, is an ordinary electric or other suitable motor 17, to one end of the main operating-shaft 18 of which are fitted (in the present instance) two sets of duplicate differential sheaves or pulleys 19 and 20, and fitted to the said slidable frame 5 at 21 is a double guide sheave or pulley 22. Also fitted to the slidable frame 12 at 23 is a single guide sheave or pulley 24, and likewise fittedat 25, between the arms of a yoke 26, is also a single guide sheave or pulley 27, said yoke having a threaded shank or stem 2S working through a suitable part of the frame 12, as shown, and provided with nuts 29 and 30, by which the yoke may be adjusted and secured at different positions vertically. The beam or timber 3 has mounted thereon the double stationary guide sheaves or pulleys 31, 32, and 33, (see Fig. 2,) while the said beam or timber l has similarly mounted thereon the single stationary guide sheaves or pulleys 31 and 35, as shown. Passing over the severallymentioned double guide sheaves or pulleys are preferably duplicate operating cables or cords 3G, by which the elevator-cage is caused to be raised and lowered, as presently explained, and in order that the directions of said cables or cords may be readily understood the same may better be traced by starting from a given point. Thus starting from @ein Figs. 1 and 2 and proceeding downwardly it will be seen that the said duplicate cables or cords first pass beneath and around the double sheave 19, thence upwardly and over the double stationarysheave 32, thence downwardly and beneath the separate sheaves 21 and 27 011 the frame 12, thence upwardly again and over the double stationary shcave 33, thence across and over the double stationary sheave 31, thence downwardly and beneath the double sheave 20, and finally upwardly and over the double sheave 22 and downwardly again to ai.

Connected to the upper part of the frame 5 at 37 is one end of an independent preferably single cable 38, which passes upwardly and over the single guide-sheaves 31 and 35, and thence downwardly and has its other end connected at 30 to the upper part of the car or cage 10. (See Fig. 1.)

Assuming the motion of the motor-shaft to be in the direction indicated by the curved arrow in Fig. 1, it will be seen that the two frames will be operated (through the medium of said double cables) in an upward direction, thereby causing the car or cage to descend, and that on reversing the direction of motion of said motor-shaft the said frames and earwill also be opera-ted reversely to that just described, it being understood, of course, that any desired form of starting and stopping devices may be employed, as well as any suitable means for regulating or controlling the motor, which latter may be of any approved form. It will also be seen that one of the duplicate operating cables or cords 36 will be maintained in a taut condition by the weight of the frame 12, while the other one of said cables or cords may always be kept in similar condition by proper adjustment of the guide-sheave 27, as already explained.

l may employ but a single continuous operating cable or cord for the two frames, as already mentioned, in which case one of each of the duplicate differential guide-sheaves herein described will be dispensed with. On the other hand,I may employ any desired number of such cables or cords, in which event the number of said correspondingly increased, as will be understood. Preferably, however, I employ dupli cate operating cables or cords, with an equal number of differential guide-sheaves therefor, together with an adjusting device for one of them, as shown.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
